摘要
利用虚拟激励法和Davenport脉动风速谱模型获得了具有非比例阻尼特征的消能减震结构在风荷载动力作用下的结构随机响应功率谱,利用首次跨越理论分析了消能减震结构在风荷载作用下的动力可靠度,算例表明消能装置可以提高结构的抗风可靠度,尤其在强风作用时效果更为明显。
Based on pseudo excitation method and Davenport′s power spectrum of wind pressu re the random response of passive energy dissipation structure was calculated,a nd the dynamic wind resistance reliability of the passive energy dissipation str ucture was analysed by appling the first-cross method.Numerical example showed dampers in structure can improve the dynamic wind resistance reliability of the passive energy dissipation structure,especially under strong wind load.
